This was made from the "Nerf Target" by stumphopper (http://www.thingiverse.com/thing:149606). I added a base to hold the revolving target. I added some length to the pegs of the target to have more room to move freely. I made the peg holes bigger to allow the target to move when hit (it was to tight). Also, i thickened the "Y" stand and added more length to the part where the holes are to avoid breaking when inserting the target in the "Y" stand and when the target moved.
